ChromaPure Professional and Colorimetry Research CR-300RH Reference Spectroradiometer
There are two color analyzers that professionals and dedicated enthusiasts generally seek: a reference spectroradiometer for the last word in colorimetric accuracy and a professional quality colorimeter. Unfortunately, such devices are not cheap. The Photo Research and Minolta reference spectros start at about $15,000 and go up to $30,000 +.
There is a new entry to the reference spectroradiometer market, the Colorimtry Research CR-300RH. This is the big brother to the CR-250 that we tested previously. We found that the CR-250 performs similarly to the the JETI spectros, in all areas except for speed. These are only sub-$10,000 spectros on the market.
The CR-300RH is considerably more expensive because it offers twice the resolution of the CR-250.
Summary
The CR-250 is one of the most affordable reference spectroradiometers available. Just mount on a tripod facing towards the source, connect to ChromaPure Professional, and then use as you would any other color analyzer. This is the highest resolution reference spectro available for under $30,000. With an optical resolution of 2nm, the CR-300 is capable of accurately measuring the most demanding light sources.
